III Acknowledgements First of all, I would like to thank Prof. Dr. Stefan Scheu, head of the Animal Ecology group (AG Scheu) for his supervision of my research work during my Ph.D. study in Technical University of Darmstadt. Clearly without his extensive help and guidance during my research period, I couldn’t have reached the goals of the present work.
